Problems solved by technology

There are two problems with this technology: first, according to the textual research in the previous text of this work, it is believed that the basic plants of Aconitum carmichaeli Debx. and Aconitum kusnezoffii Reichb. The plants of the genus Aconitum were also identified as the original plant of Aconitum grass, and the test on the release of seed dormancy did not specify which plant it was
According to Fan Yani (Investigation of germplasm resources of some plants of the genus Aconitum and research on its introduction and breeding in northern China [D]. Beijing: Beijing Forestry University, 2007.) and Zhou Lixia (Research on the resources survey and introduction and cultivation of some plants of the genus Aconitum [D]. ].Beijing: Beijing Forestry University, 2008) research, Aconitum plant seeds all have varying degrees of dormancy, generally by gibberellin seed soaking or low-temperature stratification method can remove seed dormancy, but different kinds of gibberellin and low temperature The sensitivity of the treatment is different, and the optimal concentration of gibberellin and the best treatment time to increase the germination rate of the seeds are also different. Among them, the dormancy degree of Aconitum kusnezoffii Reichb. seeds is the deepest, and the conventional treatment cannot break the dormancy.
Second, this seed treatment method can only be operated in a suitable environment in the winter of that year, and the treatment time is long, which is relatively restrictive in terms of environment and time
This method is very clear, but there is no clear discussion on the treatment temperature and the minimum treatment time, and the treatment of seeds with gibberellin increases the operation process and the cost of gibberellin is high. If the amount of seeds is large, the production cost will increase accordingly

Embodiment 1

[0039] A method for raising seedlings of Aconitum aconitum seeds, comprising the following steps:

[0040] (1) Seed pretreatment technology

[0041] After the seeds harvested in the current year are naturally air-dried, threshed and cleaned, they are mixed with fine sand with a humidity of about 30% in a ratio of 1:3. Requirements for fine sand particle size: sand that can pass through a fine sieve with an aperture of 0.8mm; judgment of fine sand humidity (about 30%): hold it in a ball, and disperse evenly after falling to the ground. Fine sand has a pH of 6.0-7.5. Put the mixed seeds in a breathable container such as a wooden box or a flower pot. First, spread wet sand with a thickness of 1.5-2.5 cm on the bottom of the container, and then put the mixed seeds and sand to 4-5 cm from the mouth of the container. Cover the top with 3.5-4.5cm of wet sand, continue to cover to make the wet sand arched, increase the covering thickness, reduce water loss, and cover the top of the ...

experiment example 1

[0055] The seedling raising methods in Example 1 and Comparative Examples 1-3 were used to raise seedlings of Aconitum aconitum, and the germination rate was detected. The test results are shown in Table 1:

[0056] The first counting time was the 3rd day of sowing, and the last counting time was the 28th day of sowing.

[0061] Note: The plant height and the number of unfolded leaves are the average of 10 plants randomly surveyed.

[0062] Conclusion: From Table 1, it can be seen that compared with Comparative Examples 1-3, the method of raising seedlings in Example 1 makes the emergence rate of Aconitum aconitum high, the u...

Abstract

The invention discloses a method for raising seedlings of Aconitum aconitum seeds, which comprises the following steps: (1) Seed pretreatment: Stratification treatment is performed on the Aconitum aconitum seeds, the treatment temperature is -5--1°C, and the treatment time is 40-45°C (2) Seedling cultivation in a container: the container is filled with a seedling substrate, which is composed of flower soil and vermiculite, and watered thoroughly; the seeds treated in step (1) are sown into the container, covered with soil, and exposed to sunlight. Cultivate under the sun; cultivate for 3 to 5 days to emerge; ensure sufficient sunlight after emergence. The present invention is aimed at characteristic Mongolian medicine plant Aconitum aconitum ( Aconitum kusnezoffii Reichb.)’s problem of difficult domestication in wild cultivation, invented a technical method for breeding seedlings through the seeds of Aconitum aconitum, improved the germination rate and emergence uniformity through precise seed pretreatment technology, and adjusted the increase through reasonable management and maintenance at the seedling stage Seedling preservation rate, and low cost, solve the technical difficulties in the breeding process of Aconitum aconitum from wild to cultivation, and realize rapid multiplication and large-scale production.

Description

technical field [0001] The invention belongs to the technical field of aconitum planting, and in particular relates to a method for raising seedlings of aconitum seeds. Background technique [0002] Aconitum kusnezoffii Reichb. is widely used in clinical medicine of Mongolian medicine. About one-third of Mongolian medicine prescriptions without Aconitum kusnezoffii Reichb. will not be available. need. Moreover, the content of alkaloids in Aconitum aconitum from different origins varies greatly, which brings great risks to clinical pharmaceuticals. [0003] There are few researches and academic reports about the planting technology of Aconitum kusnezoffii Reichb. at present, and the main methods are root tuber transplanting and sowing. Root tuber propagation has been applied in small-scale production, Long Mingwen (Cultivation technology of Aconitum aconitum [J]. Rural Economy and Technology, 2003, 10:032), Chen Yubao (Cultivation and management technology of Aconitum aconi...
